Figure 4.
Halogen-bonding interactions in the TTR·10 and TTR·11 complexes. One monomer (chain B) of the TTR tetramer is shown. Chloro groups in the two ester-forming boronates exhibit C–Cl···O108′ angles that are nearly linear and Cl··· O108′ distances (dashed yellow lines) that are 3.6–3.8 Å (Table S12). Images were created with the program PyMOL. (A) TTR·10 (PDB entry 5u4f). (B) TTR·11 (5u4g).
